Hey guys i accidently fully unscrewed the screw that changes the gears faster or slower in my revo. Just wondering how i can get it back to factory settings. And also when i took the dif casing apart to get the screw i found a loose small spring and what looks to be a ball bearing anybody know? Thanks and also whats the best engine i cam get for my revo

sounds like you're talking about the shift point screw in the tranny.....there's no such screw in either of the diffs......yes..??...no..??...........

please use the correct forums when posting on rctech.. this is a monster truck issue.. please use the monster truck forum.. i moved your post there.. thank you..

Yeah , I think you meant the transmission . You will need to take it out and dis assemble the trans case and put the spring/ball/set screw back into the 2 speed hub that sits inside the 2nd speed gear . Traxxas has a really good exploded view you can use too see how it goes together .

Alright thanks everybody for the helP really appreciate it amd to j whiting il make sure of it next time thanks

Hey another thing im looking at the picco .26 max and the os .21 tm for revo not sure of which one is better

Its allright i got it fixed but thanks for the fast reply

go with the .21 tm I put them in my Platnums this season and they have been working great. tried the big block thing for 2 years and that .21 is all the engine the revo needs.. getting the same lap times with my MT as my truggy.

Hey are you talking about the picco big block? Any ways thanks sO much!!

no I ran mostly GRP .21, great engines, just seem to have issues with the big block set hardware,{loose screws, weak mounts just simple stuff just happening at the wrong times...

Oh alright il check em out are you recomending them?

Would you recommend the grp .21 or the os .21tm for revo

And umm did u purchase the traxxas big block conversion kit or do tou have a revo

yes I used the traxxas BB kit, worked great but kind of like putting a v-8 in a vega.. real tight.. the o.s. 21 tm fits right in with no mods needed. strong engines..
